    Never had my teeth feel this clean before. Get the same clean feeling as your routine dental visit every use.

    I was skeptical this toothbrush would be worth the price but I’m pleasantly surprised. The cool/geek factor of the different modes and display is a bonus. Also, the magnetic charging base is very convenient and easy to clean. Hands down, the neatest thing ive found so far is the ios application that tracks your progress and shows you your brushing in real-time 3D. I thought it was kinda a gimick at first, but its strangly addictive and helpful. It leaves my teeth feeling dentist level clean every brushing session. Im impressed!

    For a high maintenance individual. My mouth feels great every brushing session. Bit steep on price but feels somewhat worth it.

    I purchased this one for my son. His previous Oral B toothbrush finally would not hold a charge after 10 years. I purchased an iO 9 for myself in June (after my first Oral B toothbrush stopped holding a charge after 25 years). I loved my new one so much, I bought one for him. My teeth have never felt so clean!!

    I highly recommend this toothbrush. First, I was doubting because of the price, but I am very satisfied after using it. It gives you real time feedback on how much pressure you put on your gums and you can monitor areas that you’re brushing on the app.

    Best toothbrush ever. I really do get that dentist clean feeling every time I use it. It’s expensive as crap, but you get what you pay for. Maybe opt for the mode one step down since the regular brush modes are the same.

    I think this is a good product. Even though it can be connected via Bluetooth to your phone, I opted not to do that and it works perfectly fine. I seem to be doing better on brushing my teeth since my dentist actually told me he noticed improvements compared to previous visits. I also like the smaller and more circular brush head compared to my Philips one (the 9000 model)
